COMBINATION BAYONET AND WIRE-CUTTER.

Specification of Letters Patent.

Application filed February 18, 1919. Serial No. 277,704.

To all whom it may concern:

Be it known that I, JOHN HMIRAK, a citizen of the Republic ofCzechoslovakia, residing at New York city, in the county of New York andState of New York, have invented new and useful ImprovementsinCombination Bayonets and Wire-Cutters, of which the following is aspecification.

In carrying out the present invention it is my purpose to improve andsimplify the general construction of bayonets and wire cutters and toprovide a combination bayonet and wire cutter which may be manufacturedat small cost and which will function efficiently and thoroughly eitheras a bayonet or as a wire cutter. 7

With the above recited objects in view and others of a similar nature,the invention consists in the construction, combination and arrangementof parts as set forth in, and falling within the scope of, the appendedclaims.

In the accompanying drawings The figure is a view in side elevation of acombination bayonet and wire cutter constructed in accordance with mypresent invention.

Referring now to the drawing in detail 1 designates the blade of thebayonet having cutting edges 2 and a point 3. One edge of the bayonet,at a suitable point in its length is formed with a slot 4 arranged at anacute angle to the cutting edge of the blade 1. In accordance with myinvention, the wall of the slot 4 is contiguous to the outer portion ofthe cutting edge of the blade 1 and serrated as at 5, while the innerend of the slot is formed to provide a cutting edge. Rotatably mountedat opposite sides of the slot 4 immediately in advance of the cuttingedge 6 are cutting rollers 7 which have their peripheries or cuttingedges substantially in edge to edge contact for cutting purposes.

In practice, when it is desired to use the device as a wire cutter, theslotted portion of the blade is engaged with the wire and manipulated insuch manner that the roughened or serrated wall of the slot and thecutter rollers 7 sever the wire. In the event that the wire passes thecutter rollers '7 before being severed, the cutting edge 6 at the innerend of the slot 4 engages the wire and completes the cutting thereof.

I claim 1. A bayonet blade with cutting edges havinga slot formedtherein with its mouth at one edge thereof, the inner wall of said slotbeing serrated, cutter rollers rotatably mounted at the opposite sidesof said slot adjacent to the inner end thereof and immediately inadvance of said end and having opposed cutting peripheries.

2. A device of the class described comprising a cutting blade having aslot formed therein opening into one edge thereof, the wall of said slotcontiguous of the edge of said blade being serrated, cutter rollersrotatably mounted at the opposite sides of said slot adjacent to theinner wall thereof and immediately in advance of such wall and havingthe cutting edges or peripheries substantially in edge to edge contactfor severing purposes, the inner wall of said slot being formed toprovide a cutting edge immediately behind the cutter rollerssubstantially as and for the purpose described.
